- - - - DV
      - METHOD & DESIGN
        
        3 lab experiments
      - IV
      - SAMPLE
        
        exp 1 = unknown
        
        exp 2= 12
        
        exp 3= two groups of 14(24)
        
        all undergraduates and researchers of both sex
    - - exp 2 - tested whether hearing your name in the unattended ear would be processed
      - exp 3 - tested whether being warned that recall be tested would help process none attended ear.
      - exp 1 - tested cherry's findings
- - - - 16 conditions. 12pps per condition(192)
    - - even in opaque condition a large proportion of pp failed to report the event
      - more pps noticed the unexpected event IN the EASY than the Hard condition (64:45)
      - more pps noticed the unexpected even in the Opaque condition than the Transparent condition
      - Umbrella woman = 65% Gorilla= 44%
      - across all conditions, 54% noticed and 46% failed to notice the unexpected event
    - - DV
        
        number of pps who noticed unexpected event(umbrella woman/gorilla)
      - METHOD & DESIGN
        
        lab experiment independent measures design
      - IV
        
        Umbrella woman/gorilla
        
        hard/easy task
        
        transparent/opaque unexpected event
        
        focus on black/white team
      - SAMPLE
        
        volunteer sampling of 228 undergraduates but only 192 used
    - - the degree of inattentional blindness depends on the difficulty of the primary task, and is more likely when the primary task is hard
      - observers are more likely to notice unexpected events if these are visually similar to the events they are paying attention to
      - inattentional blindness occurs more frequently in cases of superimposition as opposed to live action, but is still a feature of both
      - objects can be pass through the spatial area of attentional focus and still not 'seen' if they are not specifically being attended to
    - - to whether difficulty of affects attention
      - directly compare and opaque visual scenes
      - to investigate the effect of several factors on 'inattentional blindness'
